MICHAEL J. GRIFFIN, OF HARTFORD, CONNECTICUT.

HORSESHOE.

Application filed February 19, 1913.

To all whom it may concern Be it known that 1, MICHAEL J. GRIFIIN, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Horseshoe, of which the following is a specification.

My invention relates to the class of horseshoes that are provided with a cushion serving as an anti-slipping device and an object of my invention, among others, is to provide means whereby a cushion of comparatively inexpensive construction may be employed and one in which said cushion may be eifectually held in place in the shoe.

A shoe embodying my improvement and in the construction and use of which the objects hereinabove set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a bottom view of a shoe embodying my invention; Fig. 2 is a view in section through the same on plane denoted by dotted line 22 of Fig. 1; and Fig. 3 is a detail View in sect-ion through a portion of the shoe on plane denoted by dotted line 33 of Fig. 1.

In the accompanying drawings the numeral 5 denotes the toe portion of the sh e and 6 the heel portion thereof, the latter having laterally projecting treads 78 extending toward each other, each disposed. to leave a slight opening 9 between their ends. A groove 10 is formed in the shoe, extending around the toe and along the side parts 11, this groove 10 terminating at the heel in grooves 1213 extending across the shoe and within the tread portions 7 and 8, said grooves 12 and 13 being disposed parallel with each other and opening at each end into the groove 10.

A thin web 14 separates the grooves 12 and 13, forming one wall of each of said grooves, the opposite or outside walls of said grooves being formed by the lips 1516. The web and lips above referred to are preferably so constructed that they may be bent more or less at their edges to overlie and help retain the cushion in place, and this same result may be attained by a similar formation of the lips 17-18 of the groove 10.

The cushion is formed of a single strip of material one end of which is located in one end of one of the grooves 12 or 13, this strip extending along said groove, around Specification of Letters Patent.

the groove 10, and thence into and along the opposite groove 12 or 13 from that in which the end of the cushion above described is located.

It is very desirable in shoes of this class that a wide tread shall be provided at the heel, but in prior constructions the formation of this wide tread in a single piece considerably wider than the part of the tread extending around the shoe has proved to be very expensive. By constructing this wide tread portion at the heel to embody two grooves a single strip of material, which may be readily purchased upon the market, may be utilized with a result that a cushion comparatively inexpensive is obtained. The wide tread portion of the heel is more durable than if formed of a single piece and the construction is such that this wide tread cushion is more securely held in place, than in structures in which said part constitutes a piece of a single width. The thin web 1 1 and the lips 15-16 may be bent over at their edges in such manner as may be deemed best to hold the cushion securely in place, it being observed that this result may be readily accomplished by slight blows of a hammer without heating the heel of the shoe. It is further observed that the cushion may be readily removed and another inserted when desired.

It will be noted that the laterally extending treads arranged with a space between their ends provide a means for adjusting the shoe to hoofs of different widths, by simply bending the shoe so that the ends of the treads will be located farther apart or nearer together as conditions may require.

I claim- 1. A shoe including a main part having a groove extending therearound, laterally extending tread portions terminating adjacent to each other but with an opening between them, said tread portions having a double groove, the parts of which extend in alinement and each member of which extends into the groove in the main part of the shoe.

2. A shoe including a main part having a groove extending therearound, one end of said groove terminating in a groove extending across the heel portion of the shoe, and the other end of the groove in the main part terminatin in a second groove extending across the heel part and parallel to the first named groove in said heel part.

3. A shoe including a main part having a groove extending therearonnd, tread portions extending laterally ofthe main part at the heel of the shoe and terminating in proximity to each other but with an open ing therebetween, said tread portions'having a double groove located therein, the parts of which extend in alinement, and a thin web dividing said groovesand serving as a means for holding a cushion in place.

4:. A shoe including a body part with a groove extending therearound, tread parts extending laterally from the main part at the heel of the shoe and terminating in proximity to each other but with an opening therebetween, said tread portions having' a double groove located therein, the parts of which extend in alinement, and the members of said groove being divided byra thin web, and a cushion formed of a single piece of material located in said main groove and substantially filling the double groove at the heel portion of the shoe.

5. A shoe including a body having a groove extending therearound, laterally ex-r therein, the parts of which extend in alinement, and the members of said groove being divided bya thin web, and a cushion'formed of a single piece of material one end of which is located in the end of one of said lateral grooves, extending therethrongh, around the groove in the main part of the shoe and terminating in the other of said lateral grooves, completel filling the latter.
